I think you're doing quite well for a beginner. I have to agree that it's going a bit fast for my taste, but it's not bad. As I said, it's just my taste. Also, just confirming that Rose & David are siblings? Because I wasn't quite sure if you meant to have siblings going to prom together, that sounds a bit awkward. Anyway, my last thing is that maybe the interaction between Rose, David, and the Stranger/Martha could be tweaked. It just feels a bit rusty. Don't feel bad about my tips. Everyone has flaws. When I write, I always have to read over my previous writing to make sure my details are accurate. You're doing great. :)
